At least one light or movement sensor element is connected to the control device to detect the operation state. In one operation state, only a part (3) of the display device is activated, that displays a name or logo of the mobile telephone operator.

Description

Stromsparschaltung mittels betriebszustandsabhängiger Ansteuerung einer Anzeige­ vorrichtung eines Endgeräts für Mobile Kommunikation.Power-saving circuit by operating a display depending on the operating state Device for a mobile communication terminal.

Die Erfindung betrifft ein Endgerät für Mobile Kommunikation, beispielsweise ein soge­ nanntes "Handy" oder auch ein schnurloses Telefon. Bei diesen Geräten werden durch Auswertung von Betriebszuständen verschiedene Stromsparmodi aktiviert, die die soge­ nannte Standzeit des meist mit einer wiederaufladbaren Stromquelle betriebenen Gerätes zu verlängern. Aus diesem Grund sind diese Geräte auch meist mit einer Flüssigkristallan­ zeige ausgestattet, die einen sehr geringen Strombedarf hat.The invention relates to a terminal for mobile communication, for example a so-called called "cell phone" or a cordless phone. With these devices, through Evaluation of operating states activated various power saving modes, the so-called named service life of the device, which is usually operated with a rechargeable power source to extend. For this reason, these devices are mostly with a liquid crystal show equipped, which has a very low power consumption.

Aufgabe der Erfindung ist es, bei einem gattungsgemäßen Gerät den Stromverbrauch zu reduzieren.The object of the invention is to increase the power consumption in a generic device to reduce.

Diese Aufgabe wird mit den Merkmalen im Kennzeichenteil des Anspruchs 1 gelöst.This object is achieved with the features in the characterizing part of claim 1.

Die Abschaltung eines Teils der Anzeigevorrichtung bewirkt überraschenderweise auch bei Flüssigkristallanzeigen eine Reduktion des Stromverbrauchs. Bislang war eine solche Ab­ schaltung wohl für überflüssig gehalten worden, da der Stromverbrauch der anderen Teile eines Endgerätes auch im Standby-Modus einen weit größeren Energiebedarf hatte. Mit zunehmend effektiveren Maßnahmen zur Reduktion des Energiebedarfs im Standby-Mo­ dus wirkt sich nun jedoch auch eine solche Stromsparmaßnahme spürbar auf die Standby- Zeit aus.Switching off part of the display device surprisingly also causes Liquid crystal displays a reduction in power consumption. So far, this was an Ab circuit was probably considered superfluous because of the power consumption of the other parts of a terminal had a much greater energy requirement even in standby mode. With increasingly effective measures to reduce energy consumption in standby mode However, such a power saving measure now has a noticeable effect on the standby Time is up.

Eine vollständige Abschaltung der Anzeigevorrichtung birgt die Gefahr in sich, dass der Benutzer der falschen Meinung erliegt, beim Endgerät wäre die Energiequelle völlig er­ schöpft. Insofern sind in einer besonderen Ausführungsform alle Teile der Anzeigevorrich­ tung bis auf den Teil deaktiviert, in welchem der Name und/oder das Logo des Mobil­ funknetzbetreibers, bei dem das Endgerät gerade eingebucht ist, angezeigt wird. A complete shutdown of the display device carries the risk that the Users are of the wrong opinion that the energy source for the end device is completely him scoops. In this respect, in a special embodiment, all parts of the display device deactivated except for the part in which the name and / or logo of the mobile radio network operator with whom the terminal is currently logged in is displayed.  

Die Auswertung wenn das Endgerät in den Betriebszustand gehen soll, in welchem es die Anzeigevorrichtung teilweise bzw. ganz deaktiviert kann im Prinzip zeitabhängig erfolgen, zum Beispiel durch Messung der Zeit seit dem letzten Betätigen einer Taste. Durch zusätz­ liche Sensoren wie einen lichtempfindlichen Sensor oder einem bewegungsempfindlichen Sensor beispielsweise kann die Anzeigevorrichtung beispielsweise auch völlig abgeschaltet werden, wenn das Endgerät sich im Dunklen befindet. In diesem Fall ist eine Anzeige völ­ lig unnütz, da ein Benutzer ohne zusätzliche Hintergrundbeleuchtung, die wie allgemein aus dem Stand der Technik bekannt erst durch Drücken einer beliebigen Taste aktiviert werden kann, ohnehin nichts erkennen kann. Durch einen bewegungsabhängigen Sensor kann die Anzeigevorrichtung beispielsweise von einer Teilanzeige wieder auf eine Voll­ anzeige geschaltet werden. Dies ist beispielsweise dann sinnvoll, wenn ein Endgerät un­ beweglich, beispielsweise auf einem Tisch liegt. Durch Berühren des Endgeräts wird dann die vollständige Anzeige wieder ausgelöst.The evaluation if the terminal is to go into the operating state in which it is Display device partially or completely deactivated can in principle be time-dependent, for example by measuring the time since a key was last pressed. By additional sensors such as a light-sensitive sensor or a motion-sensitive one For example, the sensor can also be completely switched off by the sensor, for example when the device is in the dark. In this case the display is full lig useless since a user without additional backlight, which as general known from the prior art only activated by pressing any key can be recognized anyway. With a motion-dependent sensor can the display device, for example, from a partial display back to a full display. This is useful, for example, when a device is un movable, for example on a table. Then touching the terminal the full display is triggered again.

Die Erfindung wird nun an Hand eines in der Zeichnung dargestellten Ausführungsbei­ spiels näher beschrieben und erläutert.The invention will now be described with reference to an embodiment shown in the drawing game described and explained in more detail.

Fig. 3 Steuervorrichtung eines erfindungsgemäßen Endgeräts Fig. 3 control device of a terminal according to the invention

Fig. 3 zeigt eine Steuervorrichtung 6 eines Endgeräts für mobile Kommunikation an der eine Anzeigevorrichtung 1 angeschlossen ist. Mittels Steuerleitungen lassen sich zwei ge­ trennte Bereiche 2, 3 der Anzeigevorrichtung unabhängig voneinander aktivieren. An der Steuervorrichtung 6 sind zwei Sensoren, ein lichtempfindlicher Sensor 7 und ein bewe­ gungsempfindlicher Sensor 8 angeschlossen. Im Grundzustand, zum Beispiel direkt nach dem Einschalten des Endgerätes sind beide Bereiche 2, 3 der Anzeigevorrichtung 1 akti­ viert. Fig. 1 zeigt eine Anzeigevorrichtung 1 bei der beispielsweise in einem ersten Be­ reich 2 die Empfangsfeldstärke eines empfangenen Mobilfunksender mittels entsprechen­ der erster Symbole 4 und der Ladezustand des Akkumulators mittels zweiter Symbole 5 angezeigt wird. In einem zweiten Bereich der Anzeigevorrichtung 2 wird der Name 3 des Mobilfunkbetreibers, bei dem das Endgerät gerade eingebucht ist, angezeigt. Fig. 3 shows a control device 6 of a terminal for mobile communication in which a display device 1 connected. By means of control lines, two separate areas 2 , 3 of the display device can be activated independently of one another. On the control device 6 , two sensors, a light-sensitive sensor 7 and a motion-sensitive sensor 8 are connected. In the basic state, for example immediately after switching on the terminal, both areas 2 , 3 of the display device 1 are activated. Fig. 1 shows a display device 1 in which, for example, in a first loading area 2, the received field strength of a received mobile radio transmitter is indicated by means of the first symbols 4 and the state of charge of the battery is indicated by means of second symbols 5 . In a second area of the display device 2 , the name 3 of the mobile radio operator with which the terminal is currently logged in is displayed.

Wird das Endgerät, beispielsweise von einer Benutzerin in einer Handtasche verstaut, hat dies einen plötzlichen Lichtabfall in der Umgebung des Endgeräts zur Folge. Durch Aus­ wertung des lichtempfindlichen Sensors 7 erkennt die Steuervorrichtung 6 diesen Betriebs­ zustand und deaktiviert beide Bereiche 2, 3 der Anzeigevorrichtung 1. Auf eine Darstel­ lung der Anzeigevorrichtung in diesem Betriebszustand wurde aus nahe liegenden Grün­ den verzichtet, da auf der Anzeigevorrichtung nichts zu erkennen wäre.If the terminal is stowed in a handbag, for example by a user, this leads to a sudden drop in light in the vicinity of the terminal. By evaluating the light-sensitive sensor 7 , the control device 6 detects this operating state and deactivates both areas 2 , 3 of the display device 1 . A display of the display device in this operating state was omitted for obvious reasons because nothing could be seen on the display device.

Wird das Endgerät aus der Handtasche genommen und fällt wieder Licht auf den licht­ empfindlichen Sensor 7 so aktiviert die Steuervorrichtung 6 wieder beide Teile der An­ zeigevorrichtung. Durch Auswertung des bewegungsempfindlichen Sensors 8 wird nach Ablauf einer bestimmten Zeit die Anzeigevorrichtung teilweise aktiviert. Fig. 2 zeigt diesen Betriebszustand, bei dem nur noch der Name des Mobilfunkbetreibers zu erkennen ist. Dieser Betriebszustand ergibt sich beispielsweise wenn das Endgerät auf einem Tisch abgelegt wird.If the terminal is removed from the handbag and light falls again on the light-sensitive sensor 7 , the control device 6 activates both parts of the display device again. By evaluating the motion-sensitive sensor 8 , the display device is partially activated after a certain time. FIG. 2 shows this operating condition, in which only the name of the mobile operator can be seen. This operating state arises, for example, when the terminal is placed on a table.

Wie man sieht, lassen sich durch entsprechende Ausgestaltung und Programmierung der Steuervorrichtung 6 für unterschiedliche Betriebszustände des Endgeräts durch Messung von Zeitablauf und Sensoren beliebige Aktivierungsmöglichkeiten der Anzeigevorrichtung 1 einstellen. So kann - nur um eine weitere Anwendung zu nennen - nicht nur zwischen Umgebungslicht und keinem Umgebungslicht unterschieden werden, sondern auch die Menge des Umgebungslichtes ausgewertet werden, um beispielsweise bei mäßigem Umge­ bungslicht, wie man dies gelegentlich in Kneipen antreffen soll, auf eine Teilanzeige um­ zuschalten.As can be seen, appropriate activation and programming of the control device 6 for different operating states of the terminal can be set by measuring the time lapse and sensors to activate the activation device 1 as desired. So - just to name a further application - not only a distinction can be made between ambient light and no ambient light, but also the amount of ambient light can be evaluated, for example in the case of moderate ambient light, as is occasionally found in pubs, for a partial display switch on.
